Everything about backing up to tape

Yes it does.

The backup to tape job is configured as secondary job in the backup to disk job.
It's scheduled to run after the backup to disk job is ready

The situation looks unexpected, since no matter how the job is started (manually or automatically) there shouldn't be any differences. Feel free to open a ticket with our support team. Thanks.

This is the warning in the job

27-2-2014 22:11:10 :: Backup file \\DD640-CIFS\B2D\Veeam\Dagelijks 1\Dagelijks 12014-02-27T210121.vib on This server requires retry, postponing.
27-2-2014 22:11:10 :: There is nothing to backup.
27-2-2014 22:11:10 :: Job finished at 27-2-2014 22:11:10

seems like the file is not ready to backup?

But you can't select a retry for a backup to 2 job?

Bob,
According to QA department this issue was fixed based of customer’s feedback to support, however, it was very device specific. In order to get appropriate solution – please contact to our support team. Thank you.

Hi Stephen, I'm wondering what product version you're using. Is it the first job run or not? If it's sub sequential run, can you confirm that files have been copied already to tape mediums? Thanks.

Sorry, didn't catch the update reply.

I am running 7.0.0.871, and it is a job that has been ran often, and is triggered by the completition of the VMware cluster.

There would be nothing copied since the job literally just completed. It couldn't transfer the files to tape before the files are even written to disk.

If it can, Veeam is fancier than I thought!

Can you elaborate on what schedule settings are specified for a backup to tape job? As new backup files appear? After backup job? Thanks.

The job is triggered upon the completion of the other job.

The referenced error suggests that something is wrong with the drive detection mechanism. Can you confirm that drives are reflected properly in both Windows Device Manager and VB&R console? Also, with version 8 in similar situations we will provide more descriptive error message, instead of outputting somewhat confusing "0 directories...". Thanks.

Yep, all drivers are up to date, and works 95% of the time. Just some days it will not.

Engineer on our case did say he found a bug reporting the same as we have, but nothing beyond that. If you want to poke around in it you are welcome to as well. I have two identical environments, Veeam configured the exact same, both failing ocasionally.

According to our QA guys, the mentioned error most likely indicates that tape drives have dissociated from tape library or some other low-level device problem. The sporadic nature of the issue just confirms it - something happens on low-level with the device, as the result, tape job fails. May be the tape library has sort of logging system, using which you can find the root cause of this behavior? Thanks.

To summarize:
Yep, all drivers are up to date, and works 95% of the time.

That’s the root of the problem; once the drive got disconnected by any reason( for example physical malfunctioning, disconnection from the library, locking by other software) from VBR would fail with the error "Library does not contain any enabled tape drive. (System.Exception)".

Engineer on phone said its related to this, and that a bug report is filed but no ETA on any fixes.

The issue or bug from our side is that this error could be found only in the Job Log, but is not displayed in the VBR console. Instead you got “0 Directories and 0 files backed up successfully” which does not correctly indicate what happened – as you can get the same error when no new restore points were created and backup to tape job completed with nothing to backup. Problem with logging is the known issue, which is going to be fixed in next release – we sorted out several cases (like this) that require additional care.

Stephen,
As Vladimir said - you need to check the connection of the tape drive device to the VBR server, and identify why it’s sporadically going offline.
